Crown 7 is someone’s idea of an electric cigarette that prevents second-hand smoke.  Nicotine cartridges and water create “smoke” that is supposed to be equal to a regular cigarette in its effect. It is also available in a cigar and pipe model and comes with a recharger, 2 lithium batteries, and 2 replacement filters. Additional cartridges cost $10.00 each. For $99.95 and no explanation of the equivalency to a normal cig, we offer another alternative to keeping away second-hand smoke. We call it opening a window.
